test(handlers): add DB-error tests for SessionSearch and DelegationRecord

Cherry-pick of PR #1094 (test/delegate-record-db-errors) onto current staging.

- TestSessionSearch_DBError (activity_test.go): verifies SessionSearch returns 500
  when the DB QueryContext returns context.DeadlineExceeded.
- TestDelegationRecord_DBInsertFails (delegation_test.go): verifies Record returns
  500 when the activity_logs INSERT fails (WillReturnError).

Both tests use sqlmock to simulate DB failures and verify the handlers
return the correct HTTP 500 status.

Closes #1152.
